To all iti/rom t may conce/Mt.'

Be it knownV that L GEORGE HENRY CozE-Ns, a subject of the King of Great Britain, residing in the 'city of Hamilton, in the county of lVentworth, in the Province of Untario, Dominion of Canada, have invented certain new and useful Improvements in Sash-Fasteners, of which the following is a specification.

My invention rela-tes to improvements in Sash Fasteners and the Object of the invention is to provide a devicev of this nature which may be conveniently fitted to windows of the slidingtype and which vwill enable them to bc positively locked in any desired positions; and a further object is to make such a device in a cheap and simple form.

My invention consists of a bracket secured to the top of the lower sash and having locking fingers pivotally mounted therein, a notched rod carried by the upper sash and passing through bearing orifices in the bracket and inner ends of the locking fingers, said inner ends of' the locking fingers adapted to engage the notches in the rod ing normally to separate their outer ends, all as hereinafter more particularly described and illustrated in the accompanying drawings in which,

Figure 1 is a side elevation showing my yinvention mounted `upon a window, the

sashes being shown in the partly open position and in cross-section.

2 is a front view of F ig. 1 looking from the left. l

.F ig. 3 is a section of the device on the line of F ig. 1 omitting the sashes. I

F 4 is a section of the device on the line 4, 4 of Fig. 1 omitting the sashes.

Like characters of reference indicate corresponding parts in the different views.

1 is the lower sash and 2 the glass thereof.

3 is the upper sash and 4 the glass thereof'.

5 is a bracket secured to the top of the lower sash by the screws 6 and having the base 7 and the two upright side walls 8.

The bracket 5 is provided with the two bearing lugs 9 each having an orifice 10 therein7 for a purpose as will appear hereinafter? and a spring co-acting with the fingers tend.V

11 are two locking fingers which are pivs y otally mounted in the bracket by means of thepin 12 whichv extends through register'- ing orifices in the walls 8 of the bracketand orifices inV the lugs 13 of the fingers. The

outer ends 14 of the fingers are normally heldapart by the spring l5. The outer ends 14 are formed into enlarged handle portions.

The inner ends 16 of the fingers are each providedY with an orifice 17 for a purpose as will appear hereinafter.

18 1s an upright rod which is secured to I .65

of the fingers 11 and is provided along one side thereof with a se ies of horizontally disposed spaced notches 21.

22 is the partingstrip between the lower and upper sashes and 23 isV a portion of the frame of the window. Y

The method of mounting my device is as follows The notched rod 18 is passed through the orifices 10 and 17 and the bracket 5 is then secured to the lower sash.

The rod 18 is then secured in means of the end brackets 19 and screws 20.

The operation of the device is as follows lt will be apparent that the spring 15 will normally separate the ends 14 of the fingers 11 and close the ends 1G together. In this way the fingers will normally be forced into engagement with the notches 21 whenever they are in the registering position.

. Vfhen the fingers are in engagement with the notches the sashes are positively locked in-their correspondingpositions and before they can be moved up or down the fingers must be disengaged from the notches.

This can only be done by pinching the ends 14 together against the pressure of the spring 15. This separates the ends 16 and with# draws the fingers from vengagement with the notches..

place by While the ends 14 are heldpinched together the sashes may be moved to any desired positions and immediately upon release of the ngers, engagement is ag with the notches. and the sashes are again locked. i i f lt will of course/he apparent that by providing a series of notches along the entire length of the rod 18 that the sashes may he locked in practically any desired positions ranging from fully closed to fully open.

l am aware that sash fasteners somewhat similar in operation to my invention have heen devised but in these former devices the locking fingers carried by the lower sashsiinply had end engagement with a notched member carried hy the upper sash, and no provision was made forlpreve'nting relative lateral' displacement.

Such devices do not provide a positive lock since 'the side play of thesashes permits suticient movement of the sashes away from each other to cause disengagement of the tingers from the notches with t-he result that th s window falls into the closed position.

y This is entirely overcome in my` invention since hy having the rod 18 extending through the hearing-lugs 9 of the bracket 5 and also having thc rod extending through orifices Vin the locking fingers instead ot having end` en gagement only therewith, all relative side movement of the locking fingers and rod is rendered impossible sothat disengagement ofthe fingers from the notches is rendered impossible except by pinching the ends 14- together.

@ain made Also the typo of notched rod used in my fastener and the method of mounting same is' novel. p A y `My device is equally suitable toifwuse on windows fitted with weights or otherwise.

From the foregoing it will be seen' that I have devisedasash fastener for use on windows ot the type described which will he positive in operation and will also he cheap to malte and attach.

What I claim as my invention is:

In a. window, the combination with the upper and lower sashesl thereof, of an up right notched rod carried by the upperfsash and located within the plane of said saslna bracket mounted uponthe top edge of the lower sash, lugs formed integrally with the bracket and extending inwardly toward the upper sash, said lugsV having hearing orifices through which the upright .rod extends, 1 a pair of locking fingers pivotally mounted intermediately of their length in the h acliet and provided with orifices through which the upright rod extends, a spring normally separating` the outer ends of the fingers, said ngers adapted to engage the notches in the rod for'loclring the two sashes in any desired sashes. i Y GEORGE HENRY COZENS.
